Description

[Detailed description of the invention] This invention is a connection in which an intermediate frame for supporting cut-out plates, etc., is orthogonal to the vertical frame of a display case, etc., and the height position can be freely adjusted and fixed. It's about structure.

Conventionally, in this type of connection structure, a member is attached to the end of the intermediate frame to press and engage with the groove opened in the longitudinal direction of the vertical frame, and the intermediate frame is connected to the vertical frame by the press-fit connection. Although there are known devices in which the vertical frames are connected, there is a risk that the intermediate frame may shift in the longitudinal direction of the vertical frame after the connection. Also,
If the pressing force is increased too much in order to prevent such displacement, there is a risk that the groove will be deformed, and therefore the pressing force cannot be increased too much.

The present invention was made with the aim of providing a connection structure that eliminates these drawbacks, and includes a hook-shaped tip protruding from a fixture interposed in the intermediate frame, and a hook-shaped tip located in the center of the fixture. Insert a movable connecting piece that has a raised part and a notch at its tip,
With the ends of the fixing tool and the movable connecting piece inserted into the grooves of the vertical frame, tighten the screws inserted from the outside of the intermediate frame to pull the rear end of the movable connecting piece to the fixed frame, and then connect the movable piece to the fixed frame. The tip of the movable piece is opened using the protuberance as a fulcrum, and both tips are brought into pressure contact with both side edges of the groove, thereby connecting and fixing the intermediate frame to the vertical frame.

An embodiment of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a display case that is integrally assembled with vertical frames 4 erected at the corners of an upper frame 2 and a lower frame 3, respectively. Each vertical frame 4 is provided with locking portions 5', 5' by opening grooves 5, 5 of a constant width in the longitudinal direction at positions closer to the outside of two adjacent side surfaces, respectively. Note that each groove 5, 5 is used so as to face inside of the display case 1.

Reference numeral 6 denotes an intermediate frame, which has a square hole 7 formed therein, and countersunk holes 9 into which screws 8 are inserted on the outer surface near both ends.

Reference numeral 10 denotes a U-shaped side fixture to be inserted into the square hole 7 of the intermediate frame 6, and a hook is provided at each tip of the top and bottom sides of the fixture for engaging with one edge of the groove 5 of the vertical frame 4. The shaped protrusions 11, 11 are arranged in series. These protrusions 11, 11 are provided with steps 12, 12 from the upper and lower side surfaces of the fixture 10, and are made to protrude outward from each other. Furthermore, the countersunk hole 9 is formed on the side surface of the fixture 10.
A hole 13 is opened just to connect it to.

Reference numeral 14 denotes a movable connecting piece inserted into the inside of the fixing device 10, which has a raised portion 15 vertically formed on the side surface approximately in the center, and has a locking portion provided at the tip portion on the other side edge of the groove 5 of the vertical frame 4. A notch 16 is provided to engage the portion 5'. Furthermore, a screw hole 17 into which the screw 8 is screwed is bored in the side surface of the movable connecting piece 14.

Then, the fixing tool 10 is lightly hammered into the square hole 7 from the edge of the intermediate frame 6 with a wooden hammer or the like, and the step 12 is removed.
12 until they hit the upper and lower edges of the square hole 7, respectively, and then insert the movable connecting piece 14 so that its rear end touches the fixture 1.
0 until it abuts the bent side edge 10a provided at the rear end of the intermediate frame 6, and screw the screw 8 inserted from the outside of the intermediate frame 6 into the countersunk hole 9 and the countersunk hole 13 into the screw hole 17 to the extent that it will not fall out. . The assembly of the connecting member to the end of the intermediate frame 6 is now complete.

In this way, the intermediate frame 6 with the connecting members assembled at both ends is orthogonal to the vertical frame 4 at a predetermined height position, and the hook-shaped protrusions 11, 11 provided on the fixture 10 are inserted into the grooves 5,
5 and tighten the screw 8 in this state, the rear end of the movable connecting piece 14 will be drawn in the direction of contacting the inner wall of the fixture 10. , Due to this attraction, the tip of the movable connecting piece 14 opens with the raised portion 15 as a fulcrum, and the movable connecting piece 1
The notch 16 provided at the tip of the groove 5 is engaged with the locking portion 5' provided at the other end edge of the groove 5, and the fixing tool 10
The hook-shaped projections 11, 11 are also engaged with the locking portions 5' on the opposite side of the groove 5, and the notches 16 and the hook-shaped projections 11, 11 are engaged with the locking portions 5', 5' on both side edges. By pressing into contact with the vertical frame 4, the intermediate frame 6 can be connected and fixed without shifting from the vertical frame 4, and the height position can be freely adjusted.

As described above, the connection structure between the vertical frame and the intermediate frame of the present invention provides a lever action by tightening the fixing device inserted into the intermediate frame and the movable connecting piece with screws inserted from the outside of the intermediate frame. The ends of the two parts inserted into the groove of the vertical frame are opened, and the two parts are connected and fixed by pressing and joining each other to the side edges of the groove. The grooves are not deformed by force.

Furthermore, the connecting structure of the present invention has an extremely simple structure and is easy to operate, and can be fixed by tightening screws from the outside of the intermediate frame, and it is also easy to change the position by loosening the screws if necessary. It has many advantages as mentioned above.
